  1. Since nails holes are pritcheled at a black heat H13 really isn't suitable; too expensive and not shock resistant. S7 is a hot working tool steel that is known for it's shock resistance. The quick wrap of the proper hammer blow SHEARS the slug. The pritchel should be in/out of the steel quick enough that heat should not be an issue. A properly shaped pritchel should function like a punch press. Lubrication is always helpful but not necessary.
